A focused revision booklet for Advanced Higher Physics, part II of the DrG-Physics Rotational Motion series. It covers the radian, angular velocity and angular acceleration, the angular equations of motion, and the links s = rθ, v = rω and a = rα.
Every worked solution shows the relationship, the substitution and the answer with its unit, one mark at a time — the way a marker reads a script.
WHAT’S INSIDE
• Data sheet with every relationship used
• Theory with diagrams: the radian; angular velocity and acceleration; rotation meets the line
• Topic Traps: the three errors that cost the most marks
• Five fully worked questions:
– Q1 Converting a spin rate (5 marks)
– Q2 A wheel spinning up from rest (6 marks)
– Q3 A fan coming to rest (7 marks)
– Q4 Non-uniform rotation (5 marks)
– Q5 The spinning Earth (8 marks)
• Examiner’s note and Do / Don’t panel after every question
• Formula card and revision checklist
TWO EDITIONS IN ONE DOWNLOAD
• STUDY edition — every step has a “why” note explaining the reasoning
• EXAM edition — the same solutions, lean and exam-shaped
